l Specification of Letters Patent.

Application filed June 19, 1916. Serial No. 104,463.

To all whom t may concern:

' Be it known that I, ERNEST JAMES SMITH, a subject of the King of England, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Inking Mechanisms, of which the following is a specification, eference being had to the accompanyi ed to decrease the speed of the inking device relative to that of the press as the speed of the press is increased. It is another object of my' invention to provide new and im'- proved means for feeding the ink to the differentiallydriven inking device, for controlling the amount of ink retained vupon the inking device, and for taking care of the surplus ink taken from lthe inking device. It is'another object of my invention to improve mechanisms of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specifically described. That which I believe to be new ,anfd desire to cover by this application is 'set fort'h`in the claims.

In the drawings 1 Figure 1 is a fragmentary diagrammatic view showing the preferred form of my improved mechanism applied to a press; and

' Fig. 2 is a verticalcross-section taken substantially on line 2-2of Fig. 1. f

Referring to the several 'figures of the drawings in which corresponding parts are indicated by the same reference characters, 10 indicates the framework of a printing press having an inking cylinder '11 revolu-l bly mounted thereon adapted to be given a proper Supply of ink from a fountain-roller 12 by means vof an oscillating roller 13 adapted to be actuated by any suitable means not shown. Ink is ada 'ted to be sprayed-'or thrown u n the i g roller 12 from a plurality o nozzles 14 to which a rammed am'. ie, isis.

supply of ink is fed through a pipe 15 by a pump 16 operated by a shaft 17 in an inkwell 18, the shaft 17 being driven at any desired speed from: any suitable part of the press. A valve 19 is interposed' in the line of piping 15 by which the amount of inkl passingv through the pipe is limited, the surplus ink delivered by the pump 16 being returned to the well '18 through a wastepipe 20.

The ink supplied to the roller 12 from the nozzles 14vis properly spread upon the roller 12 by means of a blade 21 whichrserves also to scrape the surplus ink from the roller, the pressure of the blade 21 upon the roller 12 being regulated by means of a plurality of pressure screws 22 adjusted by any suitable mechanism. The surplus ink scraped from the roller 12 isA received by a trough 23 in which the roller 12 is located, from which trough the surplus ink is returned to the well 18 by waste-pipe 24, such surplus ink being adapted to be delivered to the well 18 through a strainer 25 of any suitable type. A scraping blade 26 is mounted in yielding engagement with the roller 12 below the nozzles 14 being adapted to scrape any lint or other foreign matter from the roller 12, such foreign matter being carried with the surplus ink through the pipe 24 and strained from the ink by the strainer 25. l The differential driving means for the roller v12l comprises a bevel-gear. 27 xed upon the shaft 28 upon which the roller 12 is mounted, meshing with a bevel-gear 29 vfixed upon a vertical shaft 30. The shaft 30 is driven through the medium of a wormgear "31 fixed thereon meshing with a worm 32 fixed upon a shaft 33 driven by a suitable electric motor 34. The speed of rotationof the motor 34 is control-led by a rheostat 35 of. any suitable type controlled by a lever 36 which is actuated by a governor 37 driven by a\ shaft 38 which in turn is driven*y in timed relation to the speed of.A thepress. The arrangement is such that the governor 37 when the' shaft 38 is not being driven serves to hold the rheostat in condition' for a fairly high s eed rotation of the motor 34. When the shaft 38 is being driven with the press, the governor 37 serves to move the arm 36 in clockwise direction in Fig. 1 so as to increase the rate of rotation of the -motor 34. As the press is speeded up, the

slowly on account of the comparatively high initial speed of the motor 34. The relationship is such that When the press reaches its normal high speed operation the motor 34: under the control of the rheostat 35 .and the governor 37 will also reach its normal high speed rotation. The eiect of the governor 37 is, therefore, to decrease the speed of the motor 34 relative to that of the press as the speed of the press is increased. f

By reason of the comparatively high initial speed oi the motor 34, when the press is being driven at its low speed preparatory to its normal high speed operation, the inking device 12 Will be driven at a comparatively high speed, serving to bring the inkl"ing mechanismquickly to a properly inkedup condition for normal operation of the press With a minimum loss of printed product by reason oi' poor inking.

What l claim as `my invention and desire to secure by Letters Patent, is-

1. lin a printing press, the combination Yof an inking device, a variable speed mechanism for driving said inking device independently of the press, and means controlled by the speed of the press for regulating the speed of driving through said variable speed mechanism.

2. lln a printing press, the combination of an inking roller, a variable speed electric motor for driving said inking roller, a

yrheostat for controlling the speed of the motor, and means controlled by the speed of the press adapted to act upon said rheostat for regulating the speed of driving through said motor.

3. lln a printing press, the combination or an inking device, means controlled by the speed of the press for delivering a variable supply of ink to said inking device, and means for driving said inking .device at a variable speed.

4. lin a printing press, the combination of an inking device, means controlled by the speed of the press for delivering a variable supply of ink to said inking device, and variable speed mechanism for driving said inking device independently of the press.

5. lln a printing press, the combination of'an inking device, means controlled by the speed of the press for delivering a variable supply ot ink to said inking device, variable speed mechanism for driving said inking naearoe device independently of the press` and means controlled by the speed of the press for regulating the speed of driving through said variable speed mechanism.

` 6. lin a .printing press, the combination of an inking device, means for delivering ink to said inking device, variable speed mechanism for driving said inking device, vand means adapted upon an increase in the speed of the press to decrease the speed of the inking device relative to that of the press.

7. lnya printingl press, the combination of an inking device, a variable speed mechanism for driving said inking device independently ot the press, a governor driven in timed relation to the speed ot' the press, and connections between said governor and said variable speed mechanism for regulating the speed of driving the inking device.

8. lln a printing press, the combination of an inking roller, a variable speed electric motor for driving said inking roller, a rheostat for controlling the speed of the motor, a governor driven in timed relation to the speed of the press, and connections between said governor and said rheostat for regulating the speed of driving through said motor.

9. lin an inking mechanism, the combination of an inking device, a nozzle adjacent to said inking device, means for forcing ink through said nozzle upon `said inking device, and means for operating said inking device at a variable speed for, controlling-the amount of ink delivered thereby.
